“…The vibration of any frequency when transferred to the human body, it is called whole-body vibration (WBV) [73]. This may be the seat of the driver, moving trains' platform, a power tool or one of several other components [74,75]. This vibration is known to cause a variety of physiological problems, including musculoskeletal, circulatory, and nervous, both acute and chronic injury, and low back pain [68,69,72,76,77].…”

Electric vehicles (EVs) are promising solutions to the problems faced by combustion engine-propelled automobiles. The futuristic transportation system would be majorly catered by battery EVs, hybrid EVs, and fuel cell EVs with a different combination of energy sources that could successfully meet the requirements of different categories of vehicle propulsion systems. However, to execute such vehicle systems with a high level of safety and comfort for the transportation of people and products, a few difficulties must be resolved. EVs of today face problems such as noise-vibration-harshness, energy storage difficulties, torque fluctuation/ripple in the power train, inadequate range, and some others. The present review paper comprehends major noise and vibration issues existing in EVs and attempts made by the researchers to find solutions to such problems. The major problem faced by the vehicle as well as by the passengers is vibration and discomfort. These vibrations if continued for a longer period might cause severe damages to the vehicle structure as well as to the passenger’s body. These issues must be thoroughly addressed by researchers to increase ride comfort, which is a crucial requirement of the hour as well.

In this paper, aiming at the problem of excessive low-frequency noise in a minibus, the SEM (Super Element Method) was applied to the NVH (Noise, Vibration and Harshness) dynamics simulation analysis of the vehicle, and the vibration and noise control schemes were proposed from the aspect of vibration transfer path to improve NVH performance. First, the relationship and difference between SEM and LFEM (Legacy Finite Element Method) were elaborated theoretically. Afterward, the legacy finite element model of the full vehicle, which comprehensively considered all related components such as BIW (Body In White), chassis, door covers, body accessories and interior and exterior trims, was established based on LFEM. Furthermore, the subsystems of legacy finite element model of the vehicle were divided into super elements based on SEM, and the differences between SEM and LFEM in model processing were discussed in detail. In addition, the modal analysis and frequency response analysis of the full vehicle were carried out by LFEM and SEM respectively, and the computational results were compared with the testing results to verify the simulation accuracy and feasibility of the SEM in solving the vehicle body dynamics problems. Meanwhile, through the comparison of simulation analysis process of SEM and LFEM in practical case, the advantages of SEM compared with LFEM were discussed in terms of computational efficiency and storage space occupied. Finally, the stiffness optimization schemes of rubber bushing in the middle of driveshaft were proposed to improve vibration and noise from the aspect of vibration transfer path, and the testing results verified the effectiveness of the optimization schemes in reducing the low frequency noise inside the vehicle. The study concluded that SEM had obvious advantages over LFEM in terms of computational efficiency and storage space occupied, while ensuring the computational accuracy basically consistent with that of LFEM.

“…That is because it is difficult to meet the complex load conditions and find suitable test sites at the same time during the test. [19][20][21] In addition, the driver needs to be skilled enough to control the vehicle under the test conditions, which poses a difficult challenge. However, the protective structures can suffer more severe damage under complex loading conditions.…”

This paper develops a simulated dynamics model focused on the vibration coupling between a heavy-duty vehicle and the protective structure of the payload and verifies it through field experiments, which monitor the dynamic response under complex driving conditions such as uneven surfaces, turning, deceleration, and excessive gradients in real time. Compared with the results of the experiments and the simulations (with numerical methods), it can be found that the model can accurately estimate dynamic response of protective structures. The maximum acceleration at the bottom of the protective structure becomes larger as the amplitude of the road surface roughness increases. Furthermore, when the vehicle turns, the vibration of the protective structure increases sharply with braking, and when the vehicle begins decelerating, the lateral acceleration of the freight increases significantly in the first few seconds. In addition, the maximum acceleration at the bottom of the protective structure increases with the increase in speed when the heavy-duty vehicle is driving on a gradient, but that increase is small when the speed exceeds 80 km/h.
